SPECXFICATION forming part of Letters Patent No. 682,739, dated September 1'?, 1901.

Applioationled August 8, 1900. Serial No. 26.310. (No model.)

To al?. whom, it muy concer-n,.-

Be it known that we, EDWARD HENRY PAR- SONS, residing at Crosby House, Maryvale road, Bournville, near Birmingham, andLES- LIE BowN TAYLOR, residing at Grange road, Bournbrook, near Birmingham,England,sub jects of the Queen of Great Britain, have invented certain new and useful Improvements in Rifle-Sights, of which the following is a specication.

The object of this invention is an improved method of constructing tangent-sights and the like for the purpose of providing a lateral motion to the sight-leaf for wind-gage purposes.

Hitherto back-sights for military rifles, to which this invention particularly relates,have been constructed with an arrangement upon the slide on the back-sight leaf for wind-gage purposes, the V or center line in this method being moved out of the center of the leaf in the lateral movementof the sight-slide; but in our improvements the lateral movement is effected by bodily moving the leaf of the back-sight across its bed, one great advantage of this new method being that in sighting either with the slide or with the bottom of the leaf, whatever lateral position the leaf may bein, an equal measure of light is always obtained on either side of the V or center line, all Vs or center lines remaining in the center of the leaf.

We will describe our method of construction with the aid of the accompanying drawings, forming part of the specification, and in which similar characters of reference indicate corresponding parts in all the views. The views are drawn to a scale of double full size.

The following description and the drawings represented refer to back sights of the character used on British government service riies.

Figure l is a plan of a tangent military backsight constructed according to our invention with the sight-leaf down in its normal position. Fig. 2 is a side elevation of same. Fig.

3 is a longitudinal section through the center of the bed with the sight-leaf omitted. Fig. 4.- is a front elevation of a back-sight with the sight-leaf raised and moved out of center for Wind-gage. Fig. 5 is a detail view of the pin or pivot. Fig. 6 is a plan of the lugs. Fig. 7 is a front View of the lugs and crosssection of the bed at a; 0c, Fig. 6. Fig. 8 isa back view of the base portion of the sightleaf. Fig. 9 is a plan of the under side or base of same.

Our method of construction consists in attaching the sight-leaf A centrally to a pin B by fitting the toe T, which is on the base of the sight-leaf A, (see Figs. 8 and 9,) into a slot S in the pin B, (see Figs. 3 and 4,) the pin B having been previously passed through lugs C upon the bed D, so that the pin B acts as a pivot to the sight-leaf A when raising or lowering the leaf A to give the dierent elevations. The bed D is so formed as to permit of the pin B traveling to right and left within the lugs C, so that when the leaf is either partly or wholly elevated the pin B, carrying with it the leaf A, can be moved laterally. The pin B projects on each side of the bed, as shown on Fig. 1, to enable the sight to be readily moved by hand across the bed. Fig. 4 illustrates the pin B moved from left to right, carrying with it the sight A out of the center. The ordinary fiat sight-spring is used to hold the sight-leaf in raised or lowered positions. The flat surface E is formed on the under side of the pin B for the spring F to bear against and keep rm the pin B, with the leaf A attached, in any lateral position across the bed.

G is a iatsurface on the pin B to receive the spring F when the leaf is in its normal lying-down position.

The lugs C, through which the pin or 'pivot B passes, are formed with spiral beveled inner edges or guide-slopes H, against which bear bevels I on the back edge of the base of the sight-leaf A, (shown in detail Figs. 8 and 9,) so that the leaf A on being lowered from its upright position, Fig. 4., presses against the guide-slopes H, and thus slides back the pivot B across the bed while being turned down until it reaches the center of the bed in its normal or lying-down position. Attaching the sight-leaf A to the pivot B in the way described enables the sight-slide K to be placed upon the leaf A from the bottom before the toe T is fitted into the slot S in the IOO pivot B, so that the top piece L may be made solid with the leaf A instead of being attached to it after the sight-slide has been placed on the leaf, as has been hitherto done with this pattern of sight. It will be obvious that when using an elevated foresight a similar arrangement for sliding it across its bed may be applied. Constructing the sight-leaf to be bodily moved across its bed by hand will enable any little inaccuracies of the weapon in connection with the sight to be readily adjusted.

Having now described our invention, what We claim as new, and desire to secure by Letters Patent, is-

1. In combination in a sight for ries, a leaf, a pivot-pin to which the leaf is secured and the pivot-ears in Which the pivot turns, the

said pivot projecting on each side of the sight When the leaf is in its central position and movable longitudinally through the said ears when either end isy pushed upon, the said leaf being moved laterally of the sight by the longitudinal movement of the pin, substantially as described.

2. In combination, the pivot-ears, the pivotpin havingr a slot, the leaf having a foot fitted into said slot and having a solid top piece and a slide carried by the leaf and adapted to be placed thereon from the foot end thereof, substantially as described.

In Witness whereof We have hereunto set our hands in presence of tWo witnesses.
